"Rider friendly" header configuration that routes the head pipes away from the rider's legs, which reduces heat and provides for a comfortable ride. Features 12mm & 18mm O2 ports, with optimum placement for dyno tuning and proper measurement of the exhaust gas concentration from the port, making the engine perform efficiently. Also eliminates the need for bung adapters used by other manufacturers which fail to properly place the sensor within the exhaust flow.

Fitted with anti-reversion louvers which eliminate the negative pulse from traveling back into the port and robbing the engine of horsepower. Full coverage, laser cut heat shields. American Made Pipes for American Made Bikes.
